Hmm....
I'm not sure... is it even a Touhou character?
I'm guessing Meira, but on the other hand, I think Meira's hair is longer than that.
This is a tough one...
Or it's Iku, or Namazu, judging by what seem to be tendrils sticking out the sides of her head.
Anyhoo, I do have to say that she looks great. I love her face and expression~ Those eyelashes you drew are always cute. :3c
I also like how you gave Erebos an even fluffier design~ You told me he's eldritch of nature, but does he have forms or powers revolving around beasts? I can't help but imagine a big, dark, eldritch canine or something like that.
